finance-automation-portfolio: Skill for Claude Code

.claude/skills/recon/SKILL.md

recon is a skill for Claude Code from sophonfinance-wq/finance-automation-portfolio. It costs 44 tokens per session (358 once invoked), scanned A, original, MIT.

A tool for matching cash and debt records between a general ledger, bank statements, and lender records. It also checks whether changes to the reconciliation package return it to its original source data.

In plain words
What is it for?
For reconciling accounts, reviewing bank and lender totals, testing correction scenarios, and generating reconciliation evidence and spreadsheets.
Why use it?
It helps find mismatches and distinguish normal timing differences from items that need review. Its assurance loop shows whether the package has drifted and whether it was restored accurately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

recon scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Cash & Debt Reconciliation Engine

Package recon_engine in cash-reconciliation/. Seed 20260331, materiality $50, always exit 0 for the base CLI (flags are an expected outcome, not a failure).

Commands (run from cash-reconciliation/)

python -m recon_engine                          # reconcile; writes evidence-log.md + xlsx
python -m recon_engine --threshold 25 --no-xlsx
python -m recon_engine.loop --demo              # ASSURANCE LOOP: restore drifted package to source
python -m pytest -q                             # 7,511 tests

Loop verdicts (recon_engine/loop.py)

PASS (0) / FLAG (0, material corrections booked for review) / FAIL (1, unconverged). Key property: fidelity, not zeroing — the scenario's genuine reconciling items (deposit-in-transit, keying error) are part of the baseline and survive the loop. Baseline = reconcile(generate_dataset(seed)), not "all clean".

Key files

  • recon_engine/engine.py — classify clean/timing/flag by account number; lender 3-part total
  • recon_engine/generate.py — frozen dataclasses; use dataclasses.replace to inject drift
  • recon_engine/loop.py — per-account resync (GL row, statements, dormant marker)
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
